Answer is: helium.

Nuclear reaction is in the inner core of the Sun and hydrogen is conveted into helium.

The inner core is the central region of the Sun and all solar energy is produced in the core by nuclear fusion.

The Sun interior is divided into three regions: the inner core, the radiative zone and the convection zone.

Helium (symbol: He) is an element with atomic number 2 (2 protons) and mass number 4 (2 neutrons; n° = 4 - 2 = 2).

Helium is created when hydrogen atoms fuse together in the sun’s core

Further explanation

Fusion and fission reactions are reactions involving atomic nucleus reactions

Fission reaction is a nucleation division reaction by firing a particle usually neutron so that it gets smaller particles of atomic nuclei.

Example:

Uranium nuclei division reaction

²³⁵₉₂U + ¹₀n -> ​​⁸⁹₃₆Kr + ¹⁴⁴₅₆Ba + 3¹₀n

In this reaction, Uranium splits into Kr and Ba isotopes and releases energy and gamma radiation

Energy is generated based on the isotope mass from the beginning of the reaction and after division

A fusion reaction is a combining reaction of 2 atomic nuclei. Usually what is often used is a reaction between the hydrogen isotope that will form Helium

³₁Ti + ²₁D -> ⁴₂He + ¹₀n

Isotopes of Hydrogen Tritium and Deuterium form Helium

At the core, the reaction applies the law of eternity

• 1. energy

the energy before and after the reaction is the same

• 2. atomic number

the number of atomic numbers before and after the same

• 3. mass number

the number of mass numbers before and after the same

Particles that play a role in core reactions include

  • alpha α particles ₂He⁴
  • beta β ₋₁e⁰ particles
  • gamma particles γ
  • positron particles ₁e⁰

The composition of the Sun's gas is dominated by about 3/4 of which is Hydrogen gas while the rest is mostly Helium and other gases such as oxygen

In the core of the Sun, hydrogen fusion reactions occur every time so that it produces enormous energy

There are two fusion reactions in the sun's core

  • proton-proton chain reaction
  • CNO cycle

The energy produced by the sun is dominated by the proton-proton chain reaction and less energy from the CNO cycle

This proton-proton chain reaction turns hydrogen into helium

The reaction stage is

  • ¹H + ¹H → ²H + e⁺ + νe + 0.16 MeV

two ¹H hydrogen protons (protons) produce ²H deuterium and an e + positron and a neutrino νe

  • e⁺+ e⁻ → 2γ + 1.02 MeV

positrons and electrons to form 2 gamma particles

  • ²H + ¹H → ³He + γ + 5.49 MeV

deuterium ²H and other protons ¹ H form Helium  ³He

This nuclear reaction occurs at very high temperatures
